ANSWER:

1800 cm³

Explanation:

Initial volume (V1) = 600 cm³

We know that the pressure is reduced to one-third of the initial pressure, therefore:


\begin{gathered} V_1\cdot P_1=V_2\cdot P_2 \\ \\ P_2=(1)/(3)P_1 \\ \\ \text{ We replacing:} \\ \\ 600\cdot P_1=V_2\cdot(1)/(3)\cdot P_1 \\ \\ 600=(1)/(3)V_2 \\ \\ V_2=600\cdot3 \\ \\ V_2=1800\text{ cm^^b3} \end{gathered}

The volume would be 1800 cm³
